Detailed Description
For a better understanding of the nature of the utility model, its description is further set forth below in connection with the specific embodiments and the drawings.
The utility model is suitable for disassembling an outer ring of a tapered roller bearing in a gearbox, and particularly relates to a tool for disassembling the outer ring of the tapered roller bearing, which comprises an ejector rod 1, a connecting rod 5 and a lifting assembly as shown in figure 1. The lifting assembly is a pull ring 6, the pull ring 6 is connected with the connecting rod 5, and the ejector rod 1 is rotatably connected with the connecting rod 5.
As shown in fig. 2, the jack 1 includes a plug 101, and a fixing portion 103 connected to the plug 101, wherein the fixing portion 103 is provided with a first connection hole 102. The ejector 101 is preferably arc-shaped, so that a bearing can be protected, and the outer ring of the bearing is prevented from being damaged in the dismounting process. The plug 101 is preferably made of copper to avoid bearing pull during disassembly. The first connecting hole 102 is a slot hole, preferably an elliptical hole. The first connecting hole 102 is designed as a slotted hole, so that the relative position of the ejector rod 1 and the connecting rod 5 can be conveniently adjusted, the length of the disassembling tool can be adjusted, and the disassembling tool is suitable for disassembling bearing outer rings with different diameters.
As shown in fig. 3, the connecting rod 5 is provided with a second connecting hole 501 and a limiting post 502. The fixing bolt 3 is connected to the fixing nut 2 after passing through the first connection hole 102 and the second connection hole 501. The second connection hole 501 is provided with an internal thread, which is matched with an external thread on the fixing bolt 3. The ejector rod 1 is rotatably connected with the connecting rod 5 and can adapt to the disassembly work of the outer rings of the tapered roller bearings with different sizes.
The limiting column 502 is provided with a limiting bolt 4. The limiting column 502 is used in cooperation with the limiting bolt 4 to limit the horizontal displacement between the first connecting hole 102 and the connecting rod 5, so that the ejector rod 1 is kept in contact with the tapered roller bearing outer ring 7. Because the tapered roller bearing outer ring 7 is annular, the tapered roller bearing outer ring 7 can be detached by utilizing the lifting assembly only by keeping the ejector rod 1 in contact with the tapered roller bearing outer ring 7.
Preferably, the two ends of the connecting rod 5 are respectively connected with the top rods 1.
As shown in figure 4, when the utility model is used, the positions of the ejector rod 1 and the connecting rod 5 are adjusted by adjusting the position of the fixing nut 2 on the fixing bolt 3, so as to adapt to the disassembly work of the tapered roller bearing outer rings 7 with different sizes. After the ejector 101 is in contact with the inner wall of the outer ring 7 of the tapered roller bearing, the fixing nut 2 and the limiting bolt 4 are adjusted, the pull ring 6 is lifted upwards after the dismounting tool is in a stable state, and therefore the outer ring 7 of the tapered roller bearing is dismounted from the box body 9 of the gear box.
It should be noted that while the utility model has been described in terms of the above-mentioned embodiments, there are many other embodiments of the utility model. It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the utility model, and it is intended that all such changes and modifications be covered by the appended claims and their equivalents.
